Power battery recycling problem solution

Power battery Scale moved nearly retired time limit. On May 17th, the ministry issued the new energy automobile power storage The battery Recycling traceability management interim provisions (draft), to further standardize power battery the whole process of information collection, the main body of each link to recycle responsibility regulatory requirements are put forward.

Estimates show that power battery "retired boom will begin this year, such as implement pilot use count by 70%, in 2020 about 60000 tons of waste batteries will waiting to be processed. Is rolling in the batch of scrap, is the emerging field in the early, power battery recycling will through the test of how?

Recycling market chaos

"We said by weight, eight Yuan a kilo, not bargaining. It is high."

"There are photos? Look at the size, model and then give you an offer, the amount can be the door closed."

"Price each 50 Yuan, the battery charge to only pull down, how much value is not."

This is a waste to buy outside Beijing south rings collection and distribution center, the reporter visits the power battery recycling at the sight.

To open multiple second-hand goods service platform, such as "cash for electric cars The lithium battery"" new energy car battery recycling information, abound.

"A few people to rent a warehouse, instant messaging, online can start recycling."Beijing saide reusing resources research institute co., LTD. General manager zhao xiaoyong, told reporters in beijing-tianjin-hebei and surrounding, henan xinxiang area, shenzhen city, guangdong province, recycling "guerrillas"."No formal process, also does not comply with the requirements of environmental protection, not to mention any technical content. Informal recycling more than regular enterprise, even a few guns in other place, not only disrupt the market, more pollution hidden trouble."

And this problem also occurs in some car scrappage enterprises."Existing scrappage enterprise is given priority to with gasoline, didn't have much experience on new energy vehicles. Because of the traffic accident, for example, scrap or did not enter the cascade utilization of directly out of the vehicle, can according to the traditional process processing."Vice President of China resources recycling association Gao Yanli admitted that since last year has received many companies such as Beijing, hebei, henan feedback, said after dismantling doubt in power battery storage, transportation, association of hope to offer help.

Power battery should go after retirement? The actual early attention."For example, the 2008 Beijing Olympics as a demonstration of the electric car, batch battery has long been scrapped. But only some manufacturers and research institutions recycling used in research and development, the rest of the batteries is unaccounted for. Gao Yanli said.

"Both from the green environmental protection, safety management, and upper cover for Angle, should strengthen the supervision of recycling as soon as possible."Zhao xiaoyong said.

Recycling subject, technology, model is only a blur

Why power battery recycling problem? In a number of industry insiders point of view, the focus of the problem is who is going to what kind of pattern, how to accept and adopt recycling are uncertain.

First of all, recycling body not in place."In accordance with the regulations, the car enterprise recovery of main body responsibility, but automakers also is not everything."The national passenger car association secretary-general Cui Dong tree, said to some extent, car companies more like the electric car "assembler", in the warranty period is responsible for the battery is normal, production supplies, secondary utilization and recycling of link, is the battery business expertise."I think, who is selling batteries, who is in charge of the battery, at least should be cooperation. Unfortunately, battery companies tend to be excluded from the recycling system, the responsibility is not clear at present."

"In addition, the vehicle into the hands of the user, property is no longer belong to the car companies. Once over the warranty period, car companies must keep back?"Zhao xiaoyong said.

Secondly, in terms of technology, recycling itself is not difficult, the difficulty lies in the post-processing technology. Learned, retired battery types, specifications, process each are not identical, and series-parallel group form, application models, using time and conditions there are diversity, disassemble complex. In most domestic application now hydrometallurgy technology as an example, in addition to the overall recovery rate is low, the recycling of strong acid, strong alkali, ammonia, etc. Easy to cause pollution.

"More is, the enterprise only get used batteries themselves, did not get the relevant data. This late to pilot use brings difficulty, disassembly, anticipation, increase the processing cost."Shandong know beans battery integration technology co., LTD., deputy managing director making said.

Finally, on the recovery mode, because of the tide "retired" temporary not large-scale, many enterprises profit problem, in the short term is difficult to achieve economies of scale.

"From the point of view of economic benefit, we these specializing recycling enterprises even those informal small manufacturer."Ganzhou city of jiangxi province hao peng tech company general manager han into a helpless admits, "only a transportation, warehousing, we strictly follow the requirements of dangerous goods, compared with the small factory walk the common logistics, piled up at random, cost a lot more."

Baic, head of the new energy related with this."Domestic haven't established mature power battery recycling system, some companies are involved, is beyond the value of battery, the lack of profit point, poor economy."

Parties to grope for the solution

Difficult to start, prospect has been in the industry generally. There are even agency predicted, power battery recycling market would be a new "draught" ten billion Yuan. At this stage how to break the ice? To establish a mature closed-loop industry chain, or recycling problem can be solved fundamentally.

Starting from the recycling subject."We should be aware, for car companies, only responsibility, no interest is a let a person feel terrible thing. How to arouse the enthusiasm of the main responsibility?"Cui Dong tree said, first of all, to set up regional comprehensive recycling system, the recycling point to the enterprises have the qualifications to do, and through strict regulation to eliminate illegal collection."At the same time, encourage car companies teamed up with battery enterprise, based on classification of battery effectively implement process, forming a complete interests chain. Accelerate the development of power battery industry chain upstream and downstream integration, make recycling a profitable business, nature inspire the enthusiasm."

Zhao xiaoyong also said, in the study of power battery recycling economy mode, industry is still in infancy."But car companies as the first responsibility, should take the initiative to establish a recycling service outlets and released, by after-sales service agencies, such as battery leasing companies together to form the recycling channels, can also cooperate with relevant enterprises, build, common recycling channels, improve the recovery rate., 4 s shops to the service station, etc., from the enterprise with the method of reverse logistics complete recovery, and form a traceability management."

"We also made many for power battery recycling."Examples of the head of the Beijing auto said, such as for different application scenarios, to retire the battery module as an emphasis, established from the whole package, module to batteries, application technology and system integration technology, and so in pilot application assessment. When the vehicle battery capacity is less than 80%, can retire into pilot using link, through the screening and to group used in energy storage system. When battery capacity is less than 40%, is entering the dismantling process, thus forming a complete set of management closed loop.

But the head is also pointed out that after the pilot fully to carry out the business model, the accumulation of experience, to deal with the real value for popularization of circular economy mode to reproduce, to avoid the rush.

"So far, the national power battery recycling companies, there are more than 400 people are looking for, to build their own channels. For businesses, which will be conducive to get battery recycling efficiency, but from the perspective of industry or society as a whole effect, inevitably cause channel repeated building, leading to social efficiency and lower utilization .In other words, no matter from the size of the market or business model, we are all still in groping stage."The director of the China battery union comprehensive Yang Qingyu remind said.
